blue arrow for the second portion of this section.A shallow RAO view with a 25 to 45 degrees
cranial angulation may be of value in displaying the distal RCA when tortuosity
is present and the "straight" RAO view is not adequate. It is also helps
"un-stack" the posterior descending and postero-lateral branches and allows
one to more clearly visualize the segment of between the two branches. In the Right Anterior Oblique or
RAO view, the camera is rotated along a vertical axis towards the patient's
right, as shown at below. It is also tilted towards the patient's head.
Thus the camera "looks" at the RCA from the right and above.

In the RAO view, the camera "looks" at the outline of the septum.
The atrio-ventricular plane is seen on edge, since it sits roughly at right
angles to the ventricular septum When
